In C#, you can use strings as an array of characters, However, more common practice is to use the string keyword to declare a string variable. The string keyword is an alias for the System.String class.
To declare an empty string.
string[] arr = new string[] {}; // empty string
Now let us see what will happen when we will print this empty string.
using System; namespace Demo { class Program { static void Main(string[] args) { string[] arr = new string[] {}; // empty string string res = String.Join(" ", arr); // let us now print the empty string Console.WriteLine("This won't print any message since its an empty string {0}", res); } } }
This won't print any message since its an empty string
